Abstract

Un corps aérodynamique utilisable pour promouvoir un écoulement laminaire et satisfaire aux exigences structurales est décrit. Une peau de panneau perforée comprend une surface intérieure et une surface extérieure du corps aérodynamique. Une structure de support à microgrilles est raccordée à la surface intérieure et définit des espaces de circulation dair permettant laspiration dair de la surface extérieure à travers la peau de panneau perforée, dans un plénum du corps aérodynamique. Des rangées de faisceaux principaux de la structure de support à microgrilles sont alignées sur des lignes terrestres orientées essentiellement dans le sens de la corde par rapport à une circulation dair sur le corps aérodynamique.
